Detailed explanation-1: -The correct answer is Drip irrigation. Drip irrigation practice leads to maximum water conservation. It delivers water and nutrients directly to the plant’s roots zone.

Detailed explanation-2: -Rainwater harvesting is one of the best method used for conserving water.

Detailed explanation-3: -Properly designed, installed, and managed, drip irrigation may help achieve water conservation by reducing evaporation and deep drainage when compared to other types of irrigation such as flood or overhead sprinklers since water can be more precisely applied to the plant roots.

Detailed explanation-4: -By drip irrigation there is no loss of water due to seepage, run-off or evaporation. Therefore, it helps in conserving water. There is not enough water for human consumption because most of the water on earth is in seas and oceans which is not potable.

Detailed explanation-5: -Drip irrigation is sometimes called trickle irrigation and involves dripping water onto the soil at very low rates (2-20 litres/hour) from a system of small diameter plastic pipes fitted with outlets called emitters or drippers.
